Enduramaxx 12500 Litre Non-Potable Round Water Tank
Product Overview
The Enduramaxx 12500 Litre Non-Potable Water Tank is a large-capacity, above-ground storage tank designed for rainwater harvesting, agricultural use, sprayer filling and general non-potable water storage. Manufactured from medium-density polyethylene (MDPE), it provides a durable and practical way to store water where mains supply is unavailable, unsuitable or not required.
With its vertical cylindrical design, lifting eyes and large access lid, the tank is designed for straightforward installation, inspection and ongoing maintenance. A dedicated upstand area also allows a float valve to be installed on site without reducing the usable capacity of the tank.
This tank is intended for non-potable applications only and must not be used for drinking water or other human-consumption purposes.

High-Capacity Non-Potable Water Storage
The Enduramaxx 12500 Litre Non-Potable Water Tank provides substantial storage for sites that need a reliable reserve of water for agricultural, commercial or industrial purposes.
It can be used to collect and store rainwater, provide water for irrigation or wash-down, and hold water for sprayer filling. Its large capacity can help reduce the frequency of refilling and provide greater flexibility where water needs to be stored in advance.
The tank is not suitable for drinking water. Where potable water storage is required, a suitable potable-rated tank should be selected instead.
Vertical Above-Ground Design
The vertical cylindrical format provides a substantial storage volume while making efficient use of the available ground area.
The tank is designed for above-ground installation and should be positioned on a suitable, stable and level base capable of supporting the tank and its contents when full. Adequate clearance should be provided around the tank for access to the lid, float valve, outlets and inspection points.
Before delivery, the installation area and access route should be checked against the tank’s overall diameter and height.

The Enduramaxx 12500 Litre Non-Potable Water Tank is suitable for a wide range of applications, including:
- Rainwater harvesting

- Horticultural applications
- Market gardens
